Abstract

The utility model relates to a it is big both to have bearing strength, and it is big to have the anti-overturning moment of bearing again, axial force is big, and reduces the simple and easy bearing that whole gyration supported the speed reducer processing degree of difficulty and be used for the gyration to support the speed reducer, is equipped with the box on worm and worm wheel meshing and the worm wheel, and the worm wheel cover is on simple and easy bearing, and simple and easy bearing cover is locked by the flange on the flange, and the flange adopts bolted connection with the box. The advantages are that: the grinding of the bearing track is reduced, the processing difficulty of the whole speed reducer is reduced, and the competitiveness of the product is enhanced.

Description

Simple bearing for rotary support speed reducer

Technical Field

The utility model relates to a it is big both to have bearing strength, and it is big to have the anti-overturning moment of bearing again, axial force is big, and reduces the simple and easy bearing that whole gyration supported the speed reducer processing degree of difficulty and be used for the gyration to support the speed reducer, belongs to gyration and supports the speed reducer and make the field.

Background

The applicant's prior patent CN205715461U entitled "dual lead worm gear photo-thermal reducer composed of simple bearings" includes a worm gear reducer, in which a worm gear adopts a dual lead worm gear and a worm adopts a dual lead worm; the worm wheel base in the double-lead worm wheel is combined with the box body base and the box body through simple bearings.

Disclosure of Invention

The design purpose is as follows: on the basis of all the prior patents of the applicant, a simple bearing which has the advantages of high bearing strength, large bearing anti-overturning moment and large axial force and reduces the processing difficulty of the whole slewing support speed reducer is designed for the slewing support speed reducer.

The design scheme is as follows: in order to achieve the above design objectives. The utility model discloses in structural design, combine through simple and easy bearing between worm wheel and the flange in the gyration is supported the reduction gear, it the utility model discloses a main technical feature. The purpose of this design is: the simple bearing is a steel wire track bearing in structural design, has the characteristics of low price, simple structure, high bearing strength, capability of simultaneously bearing overturning moment and axial force, higher precision and greatly reduced bearing cost and assembly time.

The technical scheme is as follows: a simple bearing is used for a rotary support speed reducer, a worm is meshed with a worm wheel, a box body is arranged on the worm wheel, the worm wheel is sleeved on the simple bearing, the simple bearing is sleeved on a flange, the simple bearing is locked by the flange, and the flange is connected with the box body through bolts; the simple bearing adopts a steel wire track and ball separated structure, and the pretightening force of the simple bearing can be adjusted by repairing (selecting) matching or a gasket.

Compared with the traditional rotary supporting mechanism, the utility model has the advantages that the worm wheel is combined with the flange through the simple bearing, thereby not only having low price, simple structure and high bearing strength, but also simultaneously bearing the overturning moment and the axial force, having higher precision, and greatly reducing the bearing cost and the assembling time; and secondly, the grinding of the bearing track is reduced, the processing difficulty of the whole speed reducer is reduced, and the competitiveness of the product is enhanced.
